HCID 67437824(5R,7R)-4-(4-((S)-3-(tert-butoxycarbonyl(isopropyl)amino)-2-(4-chlorophenyl)propanoyl)-1,4-diazepan-1-yl)-5-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-7-yl 4-nitrobenzoateYield 50%

Procedure

(5R,7R)-4-(1,4-Diazepan-1-yl)-5-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-7-yl 4-nitrobenzoate hydrochloride (61 mg, 0.140 mmol) and 3-(tert-butoxycarbonyl(isopropyl)amino)-2-(4-chlorophenyl)propanoic acid (48 mg, 0.140 mmol) were suspended in dichloromethane (5 mL) N,N-Diisopropylethylamine (54 mg, 0.420 mmol) was then added. HBTU (53 mg, 0.140 mmol) was added, and the resultant solution was stirred at ambient for 16 hours. After this time, the reaction mixture was quenched by the addition of saturated sodium carbonate solution and then extracted twice with dichloromethane. The combined organic portions were dried over sodium sulfate, filtered, and concentrated. The residue thus obtained was purified by silica gel chromatography to give (5R,7R)-4-(4-((S)-3-(tert-butoxycarbonyl(isopropyl)amino)-2-(4-chlorophenyl)propanoyl)-1,4-diazepan-1-yl)-5-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-7-yl 4-nitrobenzoate (50 mg, 50%). LCMS (APCI+) M+=721.1, Rt=4.51 min.
